Acknowledgements

The GOES Science Tests occur at the end of long Post Launch Test (PLT) periods for each satellite and are possible because of the cooperation of NASA and NOAA/OSD and OSO personnel, who in particular prepare the satellite schedules and enable the daily changes that are requested by the science team. Thanks as well to all who contribute to the analysis of the data collected during the Science Tests.

GOES Science Test Goals

For all GOES check-outs, the goals of the Science Test include the following:

1) To assess the quality of the GOES radiance data. This is accomplished by comparison to other satellite measurements or by calculating the signal-to-noise ratio compared to specifications, as well as assess the striping in the imagery due to multiple detectors.

2) To generate products from the GOES data stream and compare to those produced from other satellites. These included several Imager and Sounder products currently used in operations.

3) Rapid-scan and other special imagery of interesting weather cases are collected with temporal resolutions as fine as every 30 seconds for severe weather, a capability of rapid-scan imagery from GOES-R that is not implemented operationally on current GOES. For GOES-15 we plan to include a 5-minute CONUS-size sector for capturing hurricane imagery.

GOES-15 Science Test:11 August – 15 September 2010

• Five (5) weeks:– Starting: 11 August 2010– Ending: 15 September 2010

• Eight (8) pre-determined schedules (See http://rammb.cira.colostate.edu/projects/goes-p/#schedules

• Daily schedule changes (at 1630 UTC), determined by test coordinators, based on feedback from participating scientists

• GOES-15 will be located at 89.5°W, not 105°W, during the Science Test

• Afterwards, GOES-15 will likely be used before GOES-14, because of the SXI capabilities.

GOES-15 Science Test Preliminary Results

• First official GOES-15 images were collected from Imager (visible and IR) and Sounder

• Improved (4 km) resolution of 13.3 µm band required changes to GVAR format (starting with GOES-14).

• Several issues with GOES-15 data:• An issue with the first “official” Sounder images not

being received correctly at CIMSS and CIRA.• Excessive striping in Sounder band-15.• Stray light testing continuing thru Science Test.
